PE T150/T350 and RHEL7

Here (page 10, small table in lower right)
  https://linux.dell.com/files/supportmatrix/RHEL_Support_Matrix.pdf
only T550 is certified for RHEL7, T150/T350 are not.

T150/T350 are certified for RHEL8 only, on page 6.

Is this definitive? Will T150/T350 never be supported on RHEL7?

We need to know this for planning purposes.

I'd swear I had seen RHEL7 as supported a few weeks ago on this page:
https://www.dell.com/support/home/en-us/product-support/product/poweredge-t350/drivers
but now it's gone, and only RHEL8 is available.


Thanks
